ABSTRACT:
An extended range linear flow transduced with simple construction and compact size. The combination of a divergent air flow section and a linear restrictor a short distance from a flow discontinuity yields a flow transducer with linearity over an extended range of flow rates. The simple construction involves only two different size tubes joined by a funnel or step-like section with the linear flow restrictor located in the larger tube section.
